PERFORMANCE EVALUATIONS OF 3D WEB-SERVICES AND OPEN-SOURCE SOFTWARE FOR DIGITAL MODELING OF ARCHAEOLOGICAL FINDS
2016
The Structure From Motion (SFM) algorithms derived from Computer Vision community make image-based techniques a competitive and user friendly approach to obtain 3D information of real objects. These algorithms have been implemented in many 3D web-services and open-source software to develop free instruments for the reconstruction of very detailed 3D digital models. Their use is becoming very common above all in archaeological studies but their potentiality for metric application has not been tested at all. The aim of the work is to investigate the quality and the accuracy of 3D models obtained through 3D web-services and SFM open-source software. Different tests have been performed using so…
Ricostruzione virtuale dei resti archeologici: sperimentazione di approcci integrati innovativi per lo studio e la valorizzazione dell’area sacra del…
2022
Il progetto di cui si presentano i risultati è rivolto all’ambito delle Scienze applicate al Patrimonio culturale e, nella fattispecie, all’applicazione di metodologie e tecnologie innovative di ricostruzione virtuale di supporto allo studio, alla valorizzazione e alla fruizione innovativa dei beni archeologici. Esso ha richiesto, per l’acquisizione delle competenze necessarie alla sua conduzione, lo svolgimento di uno stage presso la Virtutim srl in Roma, per la formazione all’uso delle tecniche di rilievo 3D e dei software di grafica e modellazione virtuale con cui sono stati realizzati i contenuti multimediali presentati di seguito, nonché un periodo di studio all’estero, presso l’Instit…
3D survey and modelling of the main portico of the Cathedral of Monreale
2018
3D survey and modelling of Cultural Heritage allow to store a great deal of 3D data that can be managed for different purposes. 3D models can be used for documentation, restoration and knowledge of historic architectures and monuments. In this work, a 3D survey of the main portico of the Cathedral of Monreale (Palermo, Italy) was carried out. The paper presents the data acquisition process and the 3D modelling phase. The work is aimed to reconstruct a 3D model that could be used also to set up an HBIM (Heritage or Historic Building Information Modelling) of the main portico. The result of this study could be considered as a first test to implement an HBIM platform for the whole monumental c…
Computer Vision Tools for 3D Modelling in Archaeology
2013
In archaeological Cultural Heritage study 3D modelling has become a very useful process to obtain indispensable data for documentation and visualization. Nowadays the continuous request to achieve photorealistic 3D models has led to testing different techniques and methodologies to speed up both data acquisition and the data processing phase. There are many examples of surveys conducted with the use of range-based and image-based techniques, but, in the last few years, the scientific research has been increasingly moving towards automatic procedures using Computer Vision approach to reduce time during data processing. Computer Vision approach offers a great opportunity for archaeological su…
The Virtual Reconstruction of the Aesculapius and Hygeia Statues from the Sanctuary of Isis in Lilybaeum: Methods and Tools for Ancient Sculptures’ E…
2022
Thanks to recent technological developments in 3D surveys, computer graphics and virtual reality, new scenarios have been opened for the documentation and enhancement of ancient sculptures. When not totally preserved, sculptures can be digitally reproduced, modified and visualized to simulate their physical or virtual reconstruction in a non-invasive way for specialists or for dissemination aims. The virtual sculptural reconstruction process starts usually from the 3D survey of real fragments, and then continues by integrating missing parts with 3D modelling techniques by means of source evaluation. Along with primary data sources (reality-based model), secondary data sources (photos, drawi…
Identification of an LPS-Induced Chemo-Attractive Peptide from Ciona robusta
2020
Background: Previously published work has demonstrated that the LPS injection of Ciona robusta leads to the overexpression of a truncated form of an immune-related mRNA (C8short) by means of Ciona robusta (CR) alternative polyadenylation (APA) (CR-APA). Methods: The 3D structure of the C8short-derived Ciona robusta chemo-attractive peptide (CrCP) was evaluated by homology modeling. The biological activity of the CrCP was studied in vitro using a primary human dermal cell line (HuDe). Real-Time PCR was used to investigate the expression levels of genes involved in cell motility.

Structure Monitoring with BIM and IoT: The Case Study of a Bridge Beam Model
2022
The diffusion of Building Information Modelling (BIM) as a reference methodology, applied to the world of construction, leads to important changes in the design and the management of big constructions and infrastructures. However, although the BIM approach is necessary for managing the entire life cycle of a construction, today, this methodology is still rarely adopted beyond the design phase. This represents a major flaw because the management of every phase of the life cycle of buildings needs accurate preliminary planning. Certainly, one of the most complex and important phases of the life cycle of a construction is the monitoring phase, which represents a fundamental aspect for the main…
Inside The Glaciers Project: Laser Scanning Of The Grotta Del Gelo (Mount Etna, Italy)
2017
As part of activities of the “Inside the Glaciers” project, managed by an Italian team of speleologists and geologists with the purpose of studying several ice-caves in Europe and South America, a research campaign was recently carried out in Mount Etna (Sicily, Italy). This volcano is the highest active in Europe and hosts more than 200 caves including Grotta del Gelo (Ice Cave) which is located on the Northern flank of Mount Etna at an altitude of about 2040 m a.s.l. This cave was formed during the Etna’s long and most destructive eruption dated from 1614 to 1624 and is one of the most famous because it hosts a small glacier, maybe the southernmost of the Northern hemisphere. Aim of this …
Architectural library. Dioscuri Temple in Agrigento
2013
This paper presents the synthesis of research about the ICT solution for cultural heritage through the innovative technology of representation and survey. One objective was to identify a method of processing data for knowledge, dissemination and preservation of the asset. Historical analysis, surveying, photogrammetry and laser scanner, the processing of survey data and modelling are all focused to the same final purpose. The methodology developed for this application framework becomes adoptable in General for Cultural Property, which become in turn the protagonists of 3D WebGIS.
Gustavo Pulitzer Finali. Interpretazioni grafiche di una Villa sul mare, 1930.
2017
Questo studio riguarda la lettura grafica di un progetto mai realizzato di Gustavo Pulitzer Finali, una ‘Villa sul mare’, presentato alla Triennale di Monza nel 1930. Il ridisegno del progetto, necessario per la comprensione del pensiero architettonico, mostra come l’architetto triestino sia riuscito a sintetizzare l’architettura navale e quella di terra in un unico organismo plastico. Il modello digitale, strumento di indagine di spazi, ad oggi, non esplorati, fornisce alla letteratura scientifica immagini inedite del progetto di Pulitzer Finali. This study concerns the graphic reading of an unbuilt project by Gustavo Pulitzer Finali, a ‘Villa by the sea’, presented at the Triennial in Mon…
